Hi All,
I have the cisco switch WS-C4948 running IOS 12.2(46)SG and local span session configured:
sw-4948>show monitor
Session 6
---------
Type : Local Session
Source Ports :
Both : Gi1/5-11,Gi1/21
Destination Ports : Gi1/4
Encapsulation : Native
Ingress : Disabled
Learning : Disabled
the total sum (input and output) of the traffic of source ports is not equal to output rate on destination port
Any idea what's wrong?
Thank You

5 minute average measures interval of about 30 minutes. So there are two possible reasons.
1. set load-interval to 30 (seconds)
2. Counters do not correspond to the mirrored information.
As a side note: One TAC case that i saw about counters were deemed as a cosmetic bug and the results had to be read elsewhere.
